2010-08-04Rename getenv_r() into getenv_f()Wolfgang Denk
While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

2009-09-28ppc4xx: Convert PPC4xx UIC defines from lower case to upper caseStefan Roese
The latest PPC4xx register cleanup patch missed the UIC defines. This patch now changes lower case UIC defines to upper case. Signed-off-by: Stefan Roese <sr@denx.de>
2009-09-11ppc4xx: Big cleanup of PPC4xx definesStefan Roese
This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
2009-06-12General help message cleanupWolfgang Denk
Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-03-20ppc4xx: Use correct io accessors for esd 405 boardsMatthias Fuchs
This patch replaces in/out8/16/32 macros by in/out_8/_be16/_be32 macros. Also volatile pointer references are replaced by the new accessors. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Signed-off-by: Stefan Roese <sr@denx.de>
2009-01-28Command usage cleanupPeter Tyser
Remove command name from all command "usage" fields and update common/command.c to display "name - usage" instead of just "usage". Also remove newlines from command usage fields. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

2008-09-03ppc4xx: Remove obsolete or unused functions from some esd boardsMatthias Fuchs
This patch removes initdram() and testdram() from most esd 405 platforms. Some boards also have an empty dummy implementation of misc_init_f(). This is also removed. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com> Signed-off-by: Stefan Roese <sr@denx.de>
2008-06-12Change initdram() return type to phys_size_tBecky Bruce
This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
